Those certainly were very Happy Days for me. Teenagers nowadays don't know what they're missing. I feel very fortunate to have grown up with the Fonz, Richie, Ralph, Potsie (had a little crush on him) & Chachi (had a little crush on him, too). Check out the episode below - when Mork meets the Fonz! Mork & Mindy, was another one of my all-time favourite TV shows, a spin-off from Happy Days, just like Laverne & Shirley.
